IMPROVEMENT IN WATER-ELEVATORS.

Specification forming part of Letters Patent No. 208,217, datedSeptember 17, 1878; application filed August 18, 1877.

To all whom it may concern.-

Be it known that I, MARTIN VAN BUREN WRIGHT, of Fort Worth, Tarrantcounty, Texas, have invented certain new and useful Improvements inWater-Elevators, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, makingpart of this specification.

My improvement relates to that class of water-elevators in which thewater-vessels are suspended from an endless carrier (such as a chain orcord) caused to revolve by passing over a crank-wheel.

In my invention the wheel is formed of two disks or sides, whose rimsare connected by transverse bars which project beyond the periphery ofthe disks to form cogs, each alternate one of which engages thecross-bars of the carrier, and the others serve to tilt the bucket as itcomes near the top of the drivingwheel.

In the drawings, Figure 1 is a vertical section through well and curb,showing the elevator in elevation. Fig. 2 is a perspective view of onebucket, showing manner of attaching to cord. Fig. 3 is a perspectiveview of the wheel.

A represents a well or cistern. B represents the curb supporting theelevator-wheel. O is the wheel-shaft, and D a hand-crank thereon. Theshaft turns in bearings b. The driving or elevator wheel consists of twodisks, E E, connected by bars or cogs e 0, extending from the peripheryof one disk to the periphery of the other and projecting beyond theperipheries. The cogs e engage cross-bars f upon the endlessvessel-carrier F, so as to insure the revolution of the carrier with therotation of the wheel.

The carrier F, I prefer to make of some nonmctallic substance, such ashempen cord saturated with paratfine. Thus I avoid the disagreeabletaste and color imparted by iron and the dangerous qualities imparted byother metals or alloys in common use, besides providin g a cheap carrierthat may be constructed by unskilled labor.

f are cross-bars, which form the truunions of pivot-shafts on which thewater-vessels are supported or upon which they turn. The water-vessels Gare attached to the bars f by brackets g, which turn on said bars; orthey may be attached by any other suitable means.

The cups or water-vessels are preferably made of glass, as they willthen last to an indefinite time, and will impart no disagreeable ordangerous quality to the water.

The bars ff may be of wood or metal; and where glass is used for thecups, metal may be dispensed with altogether, as the attachments betweenthe bar f and the cup may be by means of projections, either eye-formedor otherwise, blown upon or attached to the glass.

Where any metal is used that comes in contact with the water its surfaceshould be of such metal or other material as to impart no objectionablequality to the water.

The bars or cogs e are saddle-shaped upon the outer edge, so as toreceive the bucket or cup G, and as the bucket comes near to its highestpoint of elevation it tilts over the support 0, and discharges the waterinto the interior of the wheel between the two disks E E. H is a troughor receiver beneath the wheel, into which the water falls, and fromwhich it runs through a spout, h. The buckets Gr ascend through anaperture, h, in the trough, having a raised flange or margin, ]L2, toprevent the descent of water through the aperture h.

I prefer to provide each bucket with a small perforation, g, to allowthe gradual escape of water, so that when the apparatus is at rest thewater will not become heated in the buckets in summer nor frozen inwinter.

At the bottom of the well or cistern the carrier F may pass aroundbeneath a guide-pulley, I.

The shaft 0 may have the usual ratchetwheel and pawl to prevent itsbackward rotation when the hand is removed from the hand-crank.

Operation: The wheel is turned. The cogs e, engaging against thecross-bar f, cause the carrier to revolve so as to raise the bucketswith their mouths upward. The buckets come in contact with the cogs e ofthe Wheel, and E, connected by chain-cogs e and tilting cogs as theyreach nearly to their highest elevae, in combination with endlesscarrier F and tion they are tilted up on the cogs e and the buckets G.

Water all emptied out before they commence T their descent, so that allthe water is poured X WRIGHT into-the trough H. Witnesses:
